This SF AreaChart visualizes a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. The chart renders an area path filled in maroon, using a smoothed curve (d3.area with curveBasis) and labeled axes for Time and Temperature. Data is loaded via d3.csv from a remote file and parsed into JavaScript Date objects. The visualization employs d3.scaleTime, d3.scaleLinear, d3.axisBottom, and d3.axisLeft, with tick lines extending across the plot for a grid effect.
